IMPROVED BRACKET-BRACE FOR. STAR-RAILS.

Specification forming part of Letters Patent No. 39,875, dated September 15, 1863.

To all whom it may concern Be it known that I, ELIJAH BETTs, of Boston, in the county of Sui'olk and State of Massachusetts, have invented a new and Improved Bracket or Brace for the Side Rails of Stairs; and I do hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a front View of my invention Fig. 2, a side View of the same, the cap or plate being in section, as indicated by the line :v x, Fig. 1.

Similar letters of reference indicate corresponding parts in the two figures.

The object of this invention is to obtain a bracket or brace for stair-rails which will admit of being adjusted io suit a horizontal rail or any degree otpitch an inclined rail may have. The ordinary brackets or braces for this purpose are composed of a singlepiece of metal and have noineans of adjustment to admit of them being adjusted to rails having different degrees of inclination, and a great deal of trouble and embarrassment are fequently experiencedin applying them.

My invention consists in applying a swivel cap or plate to the end of the bracket or brace in the manner substantially as hereinafter set forth, whereby the desired end is attained.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the body or main portion of the bracket or brace, which may be of the usual curved form and provided at its lower end with aplate, a, through which screws pass to secure it to the fixture to which it is to be attached. The outer end ofthe body or main portion A of the bracket has a swivel cap or plate, B, attached to it. This cap or platevis allowed to turn on the end of A in a plane at right angles with the end ot' A. rIhe cap or plate B is screwed tothe rail, (see Fig.. l, in which the rail is shown in red outline,) and it will be seen that the cap or plate B, in consequence of being attached t0 the body or main portion ofthe bracket by means of a swivel connection, may be attached to a horizontal rail or to one having a greater or less degree of inclination. v

The cap or plate B may be attached to the body or main portion A of the bracket or brace in various Ways. One mode is shown in Fig. 2. By referring to this gure it will be seen that the end ot A is of cylindrical form, and has a recess or groove, b, made circumferentially inv it to receive a lip, c, at the inner end of a semi-tubular box, d, which depends j ELIJAEI BETTs.
